rlhis invention relates to a co-re or mandrel suitable for winding up textile materials such as cloth or the like. According to previous practice, textile manufacturers are accustomed to cores of a denite standard size and shape, such cores having a polygonal, com- Vmonly square, hollow therethrough to receive a winding shaft or mandrel, a portion of which is correspondingly shaped. Agccording to the present invention a core of standardV size and shape is provided, this core being fabricated of various materials by which the core itself is lighter in weight, stronger and cheaper than the ordinary core.

For a more complete understanding of the invention, reference may be had to the den scription thereof which follows and to the illustration thereof on the drawing, of which,'-

Figure 1 represents in section a portion o-f a core embodying the invention.

Figure 2 is a transverse section on the line 2-2 of Figure l.

Figure 3 is an end view of the core illustrated in Figure 1.

Figure 4 is a fragmentary perspective view of an element of the interior of the core.

Figure 5 is a perspective view of a metal cap used on the end of the core.

Figure 6 is a fragmentary perspective view of a modified form of inner member for the core.

Referring to the drawing in detail, 10 rep resents a fibrous tube such as may be made, for example, by winding strips of paper spirally on a mandrel with suitable adhesives between the plies. Or the tube can be made by winding a web of wet pulp upon itself on a mandrel under pressure until the desired wall thickness is obtained. The successive turns of the web are interfelted by pressure applied during the winding so that the resultant tube has a compact wall of interfelted fiber which possesses considerable mechanical strength after being properly dried. Sucha tube may be further strengthened by suitable treatment, suc-h as saturation with sulphur, asphalt, or other suitable material. The resulting tube is light but strong and is capable of considerable abuse, `sincejlt has-tough', strong walls.` y

' According to the invention I 'may Vmak i such a tube having its external 'diameter equal to the standard diameter ofvtextile cores.

A. tube of the material described needs' only Y a relatively small wall thickness for the me-V chanical strength required forsuch purposes.. ln order to adapt such a tube for :mounting on a square driving shafulmay contructfl a polygonal central member` to be carried' therein. This member may be formed in any suitable way, as by fastening togethera pair .of sheet V'metal blanks 1l. Figure Il, each of the tube blanks may be stampedwithlugs 12 and recesses 13 along the longitudinal edges, suitable `iiaps orrears'llL` being provlded'xat the, ends forfpurposes here` Y `The blank illustratedin inafter explained; Figure4 isbent vat right angles on the/line of fold'indicated at l5,two such members beingbrought together with the lugs 12 of one "extending through .the recesses 18 of the other. V'lheilugs 12 may then-bebent around the face of the opposite member so as to clinch the two blanks together, as indicated in 'Figl ure. `2. .This .structure .may beifurther Y strengthened, if desired, by spot welding,- y V soldering or otherwise securing the lugs.4

i A VIn theends of the tubel()V suitable hollow blocks may be formed, as indicated in Figure'2. Suchblocks or'be'aring membersmay be'conveniently formedof four pieces of wood'16,'these pieces being nailedor other-l wise secured together so that `their outer sur- As shown in face is Icylindrical `to fit tightlywithinthe endof the tube 10, the inner surfaceof'` the wooden bearing member being squarel to re` oeive lthe central member formedby --the blanks ,11.1 Suitablerecessesmay be formed in the wooden bearing block 16 to allow room for the lugs 12 of the metal piece. f Y

z :Infasseinbling the core, the'central member may be inserted in the tube 10, then the bearingblocks may be forced Vinto the ends of the tube so as to hold the centrall metal member suitably centered. If desired,the blocks 16 may be secured in place by an adhesive yor by fastening elements driventhrough the tube wall. After the blocks have been inserted,
